Accumulation device for paper-like sheets

ABSTRACT

An accumulation device for paper-like sheets comprises a conveying part, a clamping part, a guiding part and an accumulating part, which are connected serially. The conveying part is used for conveying the paper-like sheet to the clamping part. The clamping part comprises a drive shaft and multiple banknote-stacking wheels fixed to the drive shaft, and every banknote-stacking wheel is provided with multiple wheel blades having the same curvature. The paper-like sheet can be clamped between any two adjacent wheel blades and rotatably conveyed to the guiding part. The guiding part receives the paper-like sheet conveyed by the clamping part and guides the paper-like sheet to the accumulating part. The accumulating part is used for accumulating the paper-like sheet conveyed by the guide part. The paper-like sheets are reliably collected among the wheel blades and prevented from scattering, and thus the paper-like sheets can be uniformly arranged in order and stacked on the accumulating part.

The present application claims the benefit of priority to Chinese Patent Application No. 201210153172.3 titled “PAPER SHEET GATHERING DEVICE”, filed with the Chinese State Intellectual Property Office on May 17, 2012, the entire disclosure of which is incorporated herein by reference.

FIELD OF THE INVENTION

The present application relates to a paper sheet gathering device, and particularly to a paper sheet gathering device that conveys paper money, checks, paper representing value and the like with vanes of stacking wheels.

BACKGROUND OF THE INVENTION

The paper sheet gathering device refers to a device that conveys paper sheets (such as paper money, checks and paper representing value) at a predetermined number (for example, 100) and gathers the same at a gathering component. In the paper sheet gathering device, paper sheets conveyed continuously are received between two adjacent vanes of the stacking wheel and thus are rotationally conveyed, such that the paper sheets are dropped and stacked on the gathering component. In the device, the paper sheets are supplied with power by conveying wheels, and are receives between any two vanes of the stacking wheel longitudinally or transversely, such that the paper sheets are rotationally conveyed with the rotation of the stacking wheel until they are conveyed to the gathering component for stacking. In the course that the paper sheets are rotated together with the stacking wheel, head portions of the paper sheet are interposed between root portions of the two adjacent vanes of the stacking wheel, while tail portions of the paper sheets are protruded out of the conveying wheel and are rotated, together with the head portions of the paper sheets, along with the stacking wheel.

In the existing paper sheet gathering device, since the interval between adjacent vanes of the stacking wheel is large, no sufficient clamping force is applied to the paper sheets such that they are rotationally conveyed, the head portions of the paper sheets are away from the root portions of the vanes of the stacking wheel increasingly under the action of the centrifugal force, thereby the paper sheets are moved out of the range between the two vanes of the stacking wheel, resulting in the straggle and irregular stacking of the paper sheets.

SUMMARY OF THE INVENTION

An object of the present application is to provide a paper sheet gathering device which achieves the reliable reception of the paper sheets between wheel vanes, and can avoid the straggle of the paper sheets received between the wheel vanes, such that the paper sheets are uniformly aligned and are stacked on a gathering component.

The present application provides a paper sheet gathering device including a conveying component, a clamping component, a guiding component and a gathering component which are connected with each other in sequence.

The conveying component is configured for conveying the paper sheet to the clamping component.

The clamping component includes a driving shaft and a plurality of stacking wheels fixedly connected to the driving shaft, and each stacking wheel has a plurality of vanes which have equal radians, thereby the paper sheet can be clamped between any two adjacent vanes and be rotationally conveyed to the guiding component.

The guiding component is configured for receiving the paper sheet conveyed by the clamping component, and guiding and conveying the paper sheet to the gathering component.

The gathering component is configured for gathering paper sheets conveyed by the guiding component.

Further, vanes of the plurality of stacking wheels have different radians.

Further, at least the vane of one of the plurality of stacking wheels has a different radian from those of the rest of the plurality of stacking wheels.

Further, the plurality of stacking wheels have the same vane opening direction.

According to the present application, by arranging a third stacking wheel having a different radian between a first stacking wheel and a second stacking wheel, the paper sheet can be reliably received between adjacent vanes. In addition, the surface of the received paper sheet can be formed with convex-concave folds, thereby the friction force between the vane and the paper sheet is increased, which can effectively prevent the paper sheet from moving away from the vanes of the stacking wheel. Thereby the paper sheet can be uniformly aligned and stacked on the gathering component. Meanwhile the straggle of the paper sheets is avoided.

DETAILED DESCRIPTION

Hereinafter, the present application will be described in detail in conjunction with the accompanying drawings, such that the object, technical solutions and advantages thereof become more apparent.

As shown in FIG. 1 which is a side view of a paper sheet gathering device according to an embodiment of the present application. The paper sheet gathering device 16 according to the present application is a device for receiving paper sheet 11 such as paper money, checks and paper representing value longitudinally or transversely, the paper sheet gathering device 16 includes a conveying component, a clamping component, a guiding component 12 and a gathering component 15 which are connected with each other in sequence.

The conveying component includes a pair of conveying rollers (10, 10′) for conveying the paper sheet 11 to the clamping component.

The clamping component includes a driving shaft and three stacking wheels 13 fixed to the driving shaft. Each stacking wheel 13 has a plurality of vanes 14 which have equal radians. The paper sheet 11 can be clamped by any two adjacent vanes, and is conveyed, with the rotation of the stacking wheel, to the guiding component.

The guiding component 12 is configured for receiving the paper sheet 11 conveyed by the clamping component, and guiding and conveying the paper sheet to the gathering component 15.

The gathering component 15 is configured for gathering the paper sheet 11 conveyed by the guiding component 12.

The operating principle of the present application is as follows: paper sheets 11 are continuously supplied to the stacking wheel 13 one by one at a certain speed and in a predetermined direction by the pair of conveying rollers (10, 10′). Then the paper sheets 11 are conveyed one by one with the rotation of the stacking wheel 13, and are then conveyed by the guiding component while right and left sides of the paper sheets 11 are abutted on the guiding component 12. In this way, the paper sheets 11 are moved along the guiding component 12 which is inclined downward in the midcourse of the conveying. Finally, the paper sheets 11 are moved away from the stacking wheel 13 and are gathered on the gathering component 15 under their own weights.

As shown in FIG. 2, the three stacking wheels 13 includes: a pair of stacking wheels, that is, a first stacking wheel 13 a and a second stacking wheel 13 a, having the same radian and fixed to the driving shaft 20 at an interval narrower than the width of the paper sheet 11; and a third stacking wheel 13 b fixed to the driving shaft 20. As shown in FIG. 3, the phase of the third stacking wheel 13 b is the same with that of the first and the second stacking wheels 13 a, but the radian of vanes 14 b of the third stacking wheel 13 b is different from that of vanes 14 a of the first and the second stacking wheels 13 a, while the opening radians are the same, so as to ensure the smooth insertion of the paper sheet 11.

The present application is characterized in that the third stacking wheel 13 b is configured in a manner that it has the same phase as that of the first and the second stacking wheels 13 a and has a radian different from that of the first and the second stacking wheels 13 a. Thereby, the paper sheet 11 moved into intervals between adjacent vanes 14 a of the first and the second stacking wheels 13 a is formed with an upwardly protruded convex fold 30 or a downwardly protruded concave fold 31 at the middle portion of the paper sheet 11 under the action of the vane 14 b of the third stacking wheel 13 b. In this way, the paper sheet 11 received between the vanes 14 a is rotationally conveyed in a state that a certain friction force is applied thereon by the convex fold 30 and the concave fold 31, which can prevent the paper sheet 11 from being moved away from the vanes 14 of the first, second and third stacking wheels 13 easily while being rotationally conveyed, and thus preventing the straggle of the paper sheets 11 being rotationally conveyed.

Furthermore, in the present embodiment, as shown in FIG. 3, the distance between tops of adjacent vanes 14 a of the first and second stacking wheels 13 a along the outer circumference is designed as p; the vanes of the third stacking wheel 13 b are designed to have the same phase as that of the vanes of the first and second stacking wheels 13 a; and the vanes 14 b of the third stacking wheel 13 b are designed to have a radian different from that of the vanes 14 a of the first and second stacking wheels 13 a, with the minimum thereof being a half pitch, i.e., ½p, while the radians of the openings are the same or slightly different, so as to ensure the smooth insertion of the paper sheets 11. However, the minimum distance of the radian is not limited to the half pitch ½p, the same effect can be obtained in cases that the minimum distance of the radian is designed to be smaller or larger than the half pitch ½p. Besides the shape of the radian is not limited to the present application, and may have any shape.

The above embodiments are only preferred embodiments of the present application, which could not be construed to limit the scopes of the claims of the present application. It should be noted that, the person skilled in the art may make many modifications and improvements to the present application without departing from the principle of the present application, and the modifications and improvements should also be deemed to fall into the protection scope of the present application.
